12 Claims.

The invention relates to sprayheads for washfountains.

In some sections of the country the water contains considerable solidsor semi-solids that in time clog the spray orifices of the sprayhead andthus interfere with its efficient operation. Furthermore, these solidscollect in the chamber behind the sprayhead and thus change the rate ofdelivery of the water through the nozzles from that originally intended.In order to obviate these difficulties it is the object of thisinvention to provide a two piece sprayhead in which the nozzle passagesand the chamber behind said passages may be readily cleaned of sedimentor foreign particles.

It is a further object of the invention to provide a sprayhead in whichthe valve for the spraying fluid opens into the chamber provided withthe spray orifices, and an impact member is interposed between the valveport and said orifices to prevent water spurting out beyond the confinesof the basin into which the sprayhead discharges when the sprayheadparts are in a cleaning position.

A further object of the invention is to provide a sprayhea-d in whichthe inlet valve has a removable seat member which forms a hold-downmeans for the spray fixture.

A further object of the invention is to provide a multi-part sprayheadin which one of the parts thereof is limited in its movement to acleaning position by a stop on the supporting standard for saidsprayhead.

The invention further consists in the several features hereinafter setforth and more particuin cleaning position;

Fig. 6 is a detail side elevation view of one of the parts shown in Fig.4;

. Fig. '7 is a detail sectional view of one of the parts shown in Fig. 1showing certain. modifications;

Fig. 8 is a detail side elevation view of the part shown in Fig. 7

Fig. 9 is a detail sectional View of another of the parts shown in Fig.1 showing certain modifications.

Referring to Figs. 1 to 3 inclusive of the drawings, the sprayheadincludes two main metal members it] and H.

The member I0 is of circular shape formed to provide a base portion l2and a top portion l3 spaced from said base portion by the integral ribsor spaced columns [4 to form a chamber ID.

The base portion 12 has a centrally disposed threaded opening ittherein, an annular upstanding impact portion I6 concentric with saidopening and a flat surface I! extending from said portion 35 to theouter cylindrical edge l8. The portion l2 has a depending annular flangeI9 having a threaded outer side which is spaced inwardly from the edgel8.

The top portion I3 is of circular formation with a centrally disposedvalve stem mounting boss 2| and a comically inclined outer edge portion22 having a lower nozzle forming surface 23.

The member II is a flanged ring having a threaded base flange 24, a baseweb 25, an upstanding fiange 26, and an. outer drip flange 24'. Theupper edge of the flange 26 is provided with a plurality of nozzleforming notches 21 which have the same inclination as the surface 23 andcooperate therewith when the parts are in assembled position to providea plurality of downwardly inclined closely associated spray orifices 28.The threaded connection between the side 20 of the member Ill and thebase flange 24 permits the parts to be assembled and held in sprayforming position, and when so assembled, a yieidable washer 29 may beinterposed between the base portions of these parts. For turning themember H relative to the member I0 one or more holes 30 may be providedin fillets in said member I l for receiving a spanner wrench or othersuitable tool.

A pipe fitting BI is formed at its upper end 32 to provide a renewablevalve seat and is threaded at 33 to removably engage the threadedopening 15 of the part It), a washer 34 being interposed between saidpart 10 and a shoulder 35 on said fitting. This fitting has an enlargedbore 36 at its lower end threaded to receive the washing fluid supplypipe 31. This fitting 3| when screwed into the part I0 acts as ahold-down means for bringing the member l0 against the upper end of thestandard 41.

A flat face rubber or suitable composition valve 38 cooperates with theseat 32 and is removably secured to its stem 39 by a screw 49, said stemhaving a threaded portion 4! engaging the threaded bore 42 of the boss2|, the upper end 43 of said stem working through a stufiing box 44 ofknown construction, the exposed end of said stem carrying an operatinghandle 45. Part of the stem is shown enclosed by a tubular member 46which is used to carry a soap tray (not shown).

The head engages a hollow tubular standard 41 whose upper end seats inan annular groove 48 in the part ill, and at some point below this endit is provided with an annular stop shoulder 49 to limit the movement ofthe member I I when it is moved to a cleaning position to prevent thering falling upon the enameled or other finished surface of the bowlbeneath it and also possible deformation of said ring.

With this construction, the turning of the stem 39 in the properdirection raises the valve 38 from its seat 32 and allows water to passinto the chamber 16 and thence through the orifices 28 in a downwardlyinclined direction and in an annularly spaced series of small streams oflow velocity since the volume of the chamber Ill acts to reduce thepressure from that in the supply pipe 37. If the orifices 28 should tendto clog, then the ring member H may be turned down to separate the partsof the sprayhead, as shown in Fig. 2, so that the orifices may bereadily cleaned. If sediment should collect in the chamber I B whichwould tend to reduce its volume and thus increase the pressure of thewater through the orifices beyond a predetermined desired value. thenthe turning down of the ring member I l to the position shown in Fig. 2where the edge 21 of said ring member is below the flat surface I! ofthe part II] permits the water flushing out the sediment in thesprayhead chamber IE3. During this flushing operation the impact member16 prevents the water from the valve controlled opening from spurtingout through the opening 5E] provided by the parts of the sprayhead intheir cleaning position beyond the confines of the basin into which thesprayhead discharges, but it does not prevent an efficient flushing ofthe chamber l. With the parts in assembled formation the drip flange 24'prevents any drip from the nozzles working down along the standard 41 asthis drip will fall ofi the lower edge of said flange.

In some types of washfountains a vent pipe passes centrally through thespray fixture, and in Fig. 4 I have shown my improved sprayhead appliedto an arrangement of this kind wherein is the centrally disposed ventpipe, 52 and 53 concentrically disposed pipes forming a water inletpassage 54, the pipe 52 being spaced from the pipe 5!. The sprayheadmember 55 is similar to the member ill and is formed to provide a baseportion I2 and a top portion [3 spaced from said base portion by theintegral ribs or spaced columns I4 to form the chamber ill".

The base portion 12 has a centrally disposed threaded flange portion [5,a flushing surface portion ll" extending to the outer cylindrical edgel8, and a depending annular flange l9 threaded to receive the upperthreaded end of the standard 4! and also provides a depending flangehaving a threaded outer side 29 which is spaced inwardly from the edgeIS.

The top portion I3 is of circular formation with a centrally disposedthreaded bore 2| for the pipe 53 and a conically inclined outer edgeportion 22 having a lower nozzle forming plain surface 23' similar tothe surface 23.

The member H is substantially identical with the member H and is aflanged ring having the threaded base flange 56, a base web 25, anupstanding flange 26' and an outer drip flange 51, the flange 25 beingprovided with nozzle notches 21' similar to the notches 21' and whichcooperate with the surface 23' to form a. plurality of downwardlyinclined closely associated spray orifices 28'. The threaded connectionbetween the flange portion 1 6' and the base flange 56 permits the partsto be assembled and held in spray forming position, and when soassembled, a yield able washer 29' may be interposed between the baseportions of these parts.

The water passing through the passage 54 is controlled in any suitablemanner usually through a mixing valve (not shown). If the orifices 28should tend to clog, then the ring member ll may be turned down as inthe first construction to separate the parts of the sprayhead so thatready access may be had to the parts forming the orifices. Ifobjectionable sediment should collect in the chamber I 0", then theturning down of the member I I to bring its edge 21 below the flatsurface l1 permits the water flushing out the sediment in said chamber.

Certain advantages of the invention may be obtained where the sprayorifices are formed wholly in either one or the other of the parts inand H. In Fig. '7 the part 58 is similar to the part II! previouslydescribed except that downwardly inclined spray orifices 59 are drilledin the lower edge portion of the part 22", similar to the part 22, andthe part 50, similar to the part II, has a smooth edge similar to theedge 23 engaging the smooth edge Bl of said part 58. In Fig. 9 the part62 is similar to the part I I previously described except thatdownwardly in part 65 is generally similar to the part II) except thatthe bottom portion 66 with its depending flange 61 does not have a partextending therefrom and instead of a smooth edge for the nozzle formingportion, the nozzle forming notches 68, similar to the notches 21, areformed in this edge. A threaded ring member 69 has a threaded flange toengage the threads of the flange B1 and a flat upper surface H whichwhen screwed down to a cleaning position, forms an extension of the flatflushing surface portion 12 of the part 65 as shown in Fig. 5. In thisform the outer edge 13 of the member 69 is a conically inclined fiatsurface which cooperates with the notches 58 when the parts are inassembled position to form downwardly inclined closely associated sprayorifices similar to 28. The part 69 has a peripheral depending flange 14to prevent drip running down the sides of the standard 41. scribedconstruction has the same advantages as that of the first describedconstruction as regards the cleaning of the spray orifices and theflushing of the pressure reducing chamber 14.

The sprayhead above described is used in connection with washfountainsof the general type shown in U. S. Patent No. 1,477,189, of December 11,1923, to Louis Schlesinger wherein the small This last destreams of lowvelocity water are directed downwardly toward the outer side of thecylindrical basin.
